Warning: This story contains distressing details
A businessman was beaten with hammers by masked men who broke into his home and threatened to kill his heavily pregnant wife unless he transferred hundreds of thousands of pounds of cryptocurrency.
Speaking to the BBC, the couple, who want to remain anonymous, described the attack as "horrific" and said they feared for their unborn baby's life.
The attackers left in a car driven by a getaway driver after the man transferred his crypto savings.
Crimestoppers are offering a £10,000 reward for information in the attack, which was captured on home security footage and is being investigated by the police.
Experts say it is one of a growing type of violent theft known as a "wrench attack" targeting cryptocurrency investors.
As crypto coins have risen in value, reports of these violent robberies linked to digital assets have emerged in the UK, France and the US.
Once funds are transferred, recovering them can be extremely difficult.
The man, who the BBC is calling James, said three intruders forced their way into their Solihull home before launching an assault which lasted 45 minutes.
"The door gets pushed open, I can see gloves coming in, balaclavas," he said.
James tried to fight the men off but they hit him in the face, head and ribs with hammers.
His wife, who was seven months pregnant, was held down on the sofa by one of the criminals.
"He's got a pillow over her face," James said. "He's literally suffocating her on the sofa. I can hear her screaming, 'I can't breathe'."
The couple still had no idea what the criminals wanted until one of the men demanded James unlock his phone and hand it over.
James said the attackers appeared to know he owned cryptocurrency, but had little understanding of how to access it.
Instead, they were taking instructions from someone else connected via a live video call.
"I can hear the guy on FaceTime saying: 'Show me everything on his phone. Show me what apps he's got'," he said.
When the caller identified a crypto wallet containing substantial funds, the threats escalated dramatically.
"He was basically saying: 'Look, if you don't send us this money now, we're going to stab your wife in the stomach and kill your baby. We're going to kill your wife'," James said.
His wife, who also did not want to be named, described the attack that happened in December last year as "horrific" and said she feared James had been killed when he was unresponsive on the floor.
"It was terrifying," she said.
The woman, in her early thirties, was expecting her third child at the time and said she feared she might lose the baby due to the stress of the attack. The baby survived and was born at full term.
The men left after James transferred his savings - hundreds of thousands of pounds of cryptocurrency - to the digital wallet of the man on the video call.
They also stole several luxury Rolex watches.
James said before they left, he heard the man on the video call tell his accomplices: "You can have 10 grand each but I am taking the rest."
Rise of the 'wrench attack'
Unlike money held in a conventional bank account, cryptocurrency is often controlled directly by the owner through digital wallets or physical storage devices.
For criminals, that combination of speed, anonymity and irreversibility can make crypto holders attractive targets.
Whilst the vast majority of cryptocurrency theft happens online through hacks and scams, crypto investigators at Chainalysis say "wrench attacks" have surged in recent years.
According to their research, $30m (£22.6m) had been stolen so far this year up to June in violent robberies, making 2026 likely to become the single-worst year for violent crypto attacks on record. Home invasions are also on the rise this year, it found.
The US, Brazil, and Thailand are hotspots but France has seen the largest number of attacks by far, as a result of a data breach at a tax office that has apparently allowed wealthy crypto holders to be located.
"The physical security assumptions that protect traditional wealth, such as bank vaults and armored cars, do not automatically apply in crypto. Often, holders keep their assets in comparatively low security setups, like self-custody wallets, that can be compromised without any institutional gatekeeper standing in the way," said researchers in their report.
James said he became an amateur investor in crypto coins in 2020 and made enough money to quit his job in 2023 to trade full time.
Now he has lost everything and is looking to get back to his traditional job.
Police have yet to identify the attackers.
Crimestoppers is offering a £10,000 reward for information leading to progress in the investigation.
Alan Edwards from the charity hopes people might have information about the three attackers, the driver who was parked outside without a face covering, or the man on the phone.
"These criminals are obviously serious and part of some kind of organised crime gang," he said.
"People might be scared to give us information but we are independent of the police and keep people completely anonymous."
The three attackers are all thought to be in their late teens or early 20s and one of them was a black male with a scar under his left eyebrow.
James said he has little hope of recovering the stolen funds, but instead wanted to see those responsible brought to justice.
He also wants his experience to serve as a warning.
"They threatened my wife and my baby," he said. "People need to understand these risks are real."

Four leading AI models discuss this article
Opening Takes
“The rising frequency of 'wrench attacks' will force a market migration from individual self-custody toward institutional-grade, third-party custody providers to mitigate physical security risks.”
This incident highlights a critical, often ignored 'physical security premium' inherent in self-custody. While crypto enthusiasts tout the 'be your own bank' mantra, they frequently neglect the fact that institutional banks provide physical protection—vaults, armed guards, and regulatory recourse—that self-custody lacks. As digital asset wealth grows, we are seeing a shift from cyber-attacks to 'kinetic' crime. This creates a massive tailwind for institutional custody solutions like Coinbase Custody or Fidelity Digital Assets, as high-net-worth individuals realize that securing millions in a mobile wallet is a massive liability. The market is underpricing the systemic risk that physical vulnerability poses to the mass adoption of self-custody.
The strongest counter-argument is that this is a localized crime trend, not a systemic failure of crypto technology, and that physical home invasions occur regardless of whether a victim holds gold, cash, or crypto.
“Wrench attacks are a violent crime problem, not a crypto market problem—they reflect rational criminal targeting of high-net-worth individuals with illiquid assets, not systemic weakness in blockchain technology.”
This article is a crime story masquerading as market analysis. Yes, wrench attacks on crypto holders are real and rising—Chainalysis data showing $30m stolen YTD in violent robberies is credible. But the piece conflates three separate issues: (1) violent crime targeting wealthy individuals, (2) crypto's custody model vulnerability, and (3) systemic risk to crypto markets. Only #2 is actually about crypto. The real story is that self-custody wallets lack the institutional gatekeeping that protects bank deposits—a known feature, not a bug, of decentralized finance. This attack says nothing about Bitcoin or Ethereum's price, adoption, or viability; it says something about security theater and target selection by organized crime. The article implies crypto is uniquely vulnerable, but $30m in physical robberies is noise compared to $14+ trillion in traditional wealth crime annually.
If wrench attacks become normalized and widely publicized, wealthy individuals may abandon self-custody entirely, accelerating migration to custodial platforms (Coinbase, Kraken, etc.), which actually strengthens institutional crypto infrastructure and reduces the 'wild west' perception that regulators dislike.
“Wrench attacks highlight self-custody risks but remain too small-scale to drive meaningful shifts in crypto valuations or mainstream adoption.”
The Chainalysis data showing $30m stolen via wrench attacks through June signals rising physical risk for self-custody holders as crypto values climb, distinct from reversible bank fraud. This could accelerate shifts toward institutional custody or multisig setups with delays, while exposing data-breach vulnerabilities like France's tax office leak. Recovery remains near-zero post-transfer, and the Solihull case illustrates attackers using live video calls to bypass technical barriers, potentially slowing retail self-custody growth even if total losses stay small relative to market size.
The $30m total is trivial against crypto's multi-trillion market cap and may reflect improved reporting rather than a genuine surge capable of deterring adoption or pressuring prices.
“The near-term price impact is uncertain, but the real takeaway is a structural shift toward insured, professional custody and security infrastructure for digital assets.”
This reads as a harrowing, crime-driven story tying violence to crypto holdings, but beware of overstating the systemic risk from a single incident. The article amplifies a 'wrench attack' narrative even as total violent crypto theft remains a small slice of crypto crime, and online hacks continue to dominate. The material impact on prices is likely muted in the near term; the bigger consequence is risk-management: higher demand for insured custody, improved self-custody hardware, and possibly tighter disclosures for holders. Watch for geographic and regulatory responses that could reprice risk for crypto wealth, not a wholesale market crash.
The data suggesting 2026 could be the worst year for violent crypto theft and the video-call coordination imply rising risk and potential sentiment damage; if more cases surface, regulators may tighten rules quicker than markets adjust.
The Debate
Responding to Claude
“Violent crime will be leveraged by regulators to force a transition from self-custody to centralized, KYC-compliant institutional platforms.”
Claude and Grok are missing the second-order regulatory impact. If 'wrench attacks' become a narrative, regulators won't just watch; they will use this as a pretext to mandate 'custodial-only' access for retail, effectively killing the permissionless nature of the asset class. This isn't just about security; it is about the state reclaiming control over private keys under the guise of 'consumer safety.' The transition to institutional custody is not just a market trend; it is a regulatory trap.
Responding to Gemini
“Mandatory custody solves wrench attacks but creates worse systemic vulnerabilities regulators aren't pricing.”
Gemini's regulatory capture thesis assumes state actors will weaponize wrench attacks as pretext—plausible, but the causality is backwards. Regulators already want custody mandates for AML/KYC reasons; violent crime is convenient cover, not the driver. The real risk: if custody becomes mandatory, it centralizes systemic failure points (exchange hacks, regulatory freezes) that dwarf wrench attacks. We'd trade distributed physical risk for concentrated operational risk. That's not safer—it's just different.
Responding to Gemini
“Data leaks, not violence, are the likelier driver of rules that quietly limit self-custody.”
Gemini's regulatory trap argument skips that the $30m wrench total is too modest to justify custody mandates on its own. The France tax leak Grok noted supplies a stronger KYC pretext for data-driven rules that erode privacy without banning self-custody. That route lets regulators pressure holders via disclosure while leaving physical risk unaddressed, creating a slower but more durable constraint on permissionless use than outright bans.
Responding to Gemini
“Regulatory push for custody is likely fragmented and may concentrate risk rather than kill self-custody outright.”
Gemini's 'regulatory trap' assumes a uniform push to custodial access. In reality, the regulatory landscape is fragmented; some markets will embrace hybrid custody, and insist on disclosures/AML/KYC without banning self-custody. A mandate could backfire by centralizing risk at a few incumbents, inviting concentration risk and network fragility. Meanwhile, insurance, multisig, and hardware wallets can coexist with self-custody, preserving permissionless features where policy allows.
